Crash but no crash log!

Newbie & Debugging Questions
#1

So I am at a point where my game simply exits with some strange error code:


Java Result: -1073741819

There is no Java stack trace, no OpenGL error, and no JVM crash log.

Really not sure what to do here. How do I debug this?

I have a rough idea of what code is causing this, but I guess I’m wondering if I can get more information… Otherwise this will be quite difficult to debug.

EDIT: As far as I can tell, calling render() and/or draw() in this class: https://github.com/sci4me/SciCraft/blob/sgl/src/main/java/com/sci/craft/client/render/world/RenderChunk.java causes this to happen.

#2

Use break points and step through the code, you will then find what line causes the crash, and you can work it out from there.

#3

It crashes when glDrawArrays is called. But a few draw() calls succeed before it crashes… so… what? :stuck_out_tongue:

Really not sure what’s going on. Will keep looking but… idk if I’ll find it.

#4

Does it always crash after the same amount of calls? Is it always on the same object? I assume render() gets called only once per chunk? We probably need to see how you generate the chunk before passing it to RenderChunk

#5

Try replacing


                glVertexAttribPointer(0, 3, GL_FLOAT, false, 20, 0);
		glVertexAttribPointer(1, 2, GL_FLOAT, false, 20, 12);

		glBindBuffer(GL_ARRAY_BUFFER, this.vbo);

to


                glBindBuffer(GL_ARRAY_BUFFER, this.vbo);
                glVertexAttribPointer(0, 3, GL_FLOAT, false, 20, 0);
		glVertexAttribPointer(1, 2, GL_FLOAT, false, 20, 12);

Not sure if its your issue but it is wrong

Oh my god I think that fixed it! (It isn’t rendering right yet but that’s gotta be my fault somewhere else in the code). It isn’t crashing! :smiley:

Thank you so much!!!
